An ex enforcer for a small crime family in New York, Jack cleaned up his life after his daughter was born and his wife was killed in a car accident. He now runs a small tavern in Hoboken, New Jersey with his daughter Clementine.
He spends almost all of his time attempting to take care of Clem, though he's not very good at it. He's over protective and slightly neurotic, which has lead to more than a few fights in his bar with customers who've leered at her. He does his best to hide his former line of work from her, though the amount of former family members who come to the bar doesn't do much to help that.
